A poll of economists by Bloomberg expected GDP in the world's largest economy to be 2.5 per cent.

Dennis de Jong, managing director at UFX.com, said the numbers show America is "facing a new set of challenges in sluggish growth and weak spending."

He added: "Regaining momentum in the wake of an unsettled European market will be the next challenge for Janet Yellen and co. If the US economy can get back on track and prove to be resilient in the face of Brexit then Yellen may just think it’s time for another interest rate hike come autumn."
